Well still in every game I have played even though they do get high accuracy and block/dodge they still die easily and have thier downsides. I dunno I love my archer either way but Dex should be for ranged damage imo.
Even if Dex did equal power for bows or if it didnt. Give it a few months when poeple find out what build lvls the fastest, everyone will have that build. Its how all games are.
